So excuse me for this probably very obvious question, but I'm new to all this. Anyway I'm not quite sure how I figure out what I need. I need something that I can listen to Medicine Hat Fire Dept. I found the channels here on Radio Reference, but I'm not sure what to do with that info other than enter it into a scanner. So if you can tell me how to know what I need, or recommend a scanner, that'd be great. Even better if I can listen to other emergency services and aircraft.
